Photoshop cc 2017: UI scaling needs 150%

I'm really disappointed to see that the HiDPI UI scaling in Photoshop CC 2017 Windows is still broken/useless :( This has been reported multiple times without any response from Adobe.

Why it doesnt work: 4K screens works best with 150% scaling, Photoshop only lets you choose 200% which is good for 5K screens or 100% which is completely useless on 4K screens. So you have to choose between stupidly large UI or tiny UI.In addition, Photoshop on Windows, as the ONLY adobe program, isn't capable of adapting, when moving it from one screen to another (despite having an "Auto" button in Preferences)...You still have to restart the program when making a change. This makes it impossible to move Photoshop from a 4K screen over to a smaller res screen such as a Cintiq Tablet without restarting Photoshop every time!!

Currently I'm still forced to use a hack that forces Photoshop not to use the HiDPI UI and revert back too standard UI and let Windows rescale the UI as regular pixel blurry scaling. But this is rather tragic, it makes your HiDPI UI feature a nearly useless feature.

Come on Adobe! - Please can you respond and acknowledge this? So sick of every bug report I post is completely ignored.

Update: As of 10/25/17, we are closing this program to new applicants. We have a large number of participants already. Thank you to everyone who registered!

The Photoshop team has been listening to your many requests for better scaling options on Windows, and we’re happy to announce that we are ready for beta testing on this feature. Because of the large scale changes involved in this feature, we want to make sure people have the opportunity to test it out before it’s released.

All Windows customers are welcome to join and test, but please note that you will need to have Windows 10 Creators Edition installed in order to use the new continuously scalable user interface and per-monitor scaling. Windows 7, 8 and prior versions of Windows 10 will only support 100% and 200% - as the continuously scalable user interface requires APIs only available in Creators Edition.
